VALVE FOR GAS-BURNERS.

Specification of Letters Patent. Patented 313, 24 1914, Applicationfiled October 26, 1912.

Serial No. 727,865.

ing purposes, and the object is to provide a new and improved valve forgas burners arranged to permit convenient adjusting with a view toregulate the amount of gas passing from the service pipe to the burnerand to be automatically closed by a movable member of a stove so thatthe gas is shut off from the burner.

For the purpose mentioned use is made of a valve body having a gaspassage adapted to be connected at one end with a gas supply and at theother end with the burner, the body also having a conical seatintersecting the said passage, and the said seat is engaged by a conicalsleeve having adiametrical opening in register with the gas passage, thesleeve also having a central bore intersecting the said opening, acylindrical valve slidable in the bore of the sleeve and having anannular groove and a collar on the upper portion of the said valve andnormally seated on the top of the said sleeve, a

top cap screwing on the upper end of the upper portion of the valve, aspring in the cap and bearing on the said collar, a nut screwing on thelower end of the valve and adapted to abut against the under side of thesaid sleeve to limit the upward sliding movement of the valve.

A practical embodiment of the invention is represented in theaccompanying drawing forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure l is a sectional side elevation of the valve; and Fig. 2 is asectional plan view of the same on the line 22 of Fig. 1.

The valve body A is provided with a gas passage B adapted to beconnected at one end with a gas supply pipe and at the other end with aburner. The body A is provided with a conical seat F intersecting thegas passage B and in the said seat F is seated a conical sleeve Gprovided with a diametrical opening G in register with the gas sleeve Gis in which is mounted to slide a cylindrical .valve J provided with anannular groove J inormally out of register with the opening Gr ibutadapted to move into register with the said opening to allow passage ofthrough the gas passage B from the pipe to .the burner. the'valve J isprovided with a collar J 2 normally seated on the top of the sleeve G,that is, at the time the annular low the opening G .the under side ofthepassage B, as plainly indicated in Fig. 1. On the upper end of thesleeve G screws a capgI-I and on the lower end of the sleeve G screws anut I abutting against the under side of the valve body A so that thesleeve G is securely fastened in position on the valve body A by the useof the nut I. The provided with a central bore G supply The upperportion of groove J is beand out of register with the same, a spring Kbearing with its other end against the under side of the cap H to nor- I:mally hold the valve J in closed position.

The upper portion of the valve J extends through the cap H and isprovided on the threaded terminal J to be locked in place nut L isengaged by the forked end N of a lever N fulcrumed at N 2 on a bracket NThe free end of the lever .N is adapted to extend into a stove so as tobe engaged and operated by a movable part thereof. said sleeve andthrough which extends the In order to limit the upward movement of thevalve J the lower reduced threaded portion J thereof is provided with anut P adapted to abut against the under side of the sleeve G to limitthe upward movement of the valve J v at the time the latter is raised bythe action of the lever N. Now by adjusting the nut P on the threadedportion J the groove J may be moved into more or less register with theopening G at the time the valve J is raised to its limit by the actionof the lever N. A jam nut P screws on the threaded portion J against thenut P to lock the latter in the adjusted position. A cap Q, ispreferably screwed on the lower end of the sleeve Gr so as to inclosethe nuts P, P and the lower portion of the threaded end J of the valve Jto prevent unauthorized persons from tampering with the position of thenut P.

In order to permit the user of the gas stove to turn off the gas fromthe burner use is made of a handle R terminating in a ring the gas Onthe collar J rests one end of with a nut L adapted by a jam nut L, and

R encircling the sleeve G intermediate the body A and the lower end ofthe cap H, and the said ring R is provided with a lug or key R extendinginto a groove G formed on the sleeve G so that when the operator turnsthe handle R a turning motion is given to the sleeve G to move theopening Gr out of register with the gas passage B to cut of? the gasfrom the burner whenever it is desired to do so. Normally the sleeve Gis in the position shown in Fig. 1 so that the opening G is in registerwith'the gas passage B.

It is understood that when the valve J is in lowermost position the gassupply to the burner is cut 0H and when the lever N is operated then thevalve J is raised and the groove J is moved into register with theopening G, as previously explained, to allow gas to flow from the supplypipe to the burner. By adjusting the nut P the amount of the upwardmovement of the valve J can be regulated so that the groove J moves moreor less in register with the opening G to control the amount of the gaspassing through the passage B at the time. By having the nut Ladjustable on the upper threaded end J 3 of the stem J the lever N canbe placed in proper position relative to the movable member of thestove. 7

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. A valve, comprising a valve body having a fluid passage, and a seatintersecting the said passage, an open ended sleeve mounted to turn inthe seat and provided with openings adapted to register with the fluidpassage of the body, a valve mounted to slide in the sleeve and having apassage adapted to register with the sleeve openings, said valveprojecting beyond the ends of the sleeve and provided with stops forlimiting the sliding movement thereof, a spring for holding the valvewith its passage out of register with the sleeve openings, means forsliding the valve to bring its passage in register with the openings ofthe sleeve, and means for turning the sleeve to bring its openings inand out of register with the fluid passage of the body.

2. A valve comprising a valve body having a fluid passage and a conicalseat intersecting the passage, an open ended conical sleeve in the seatand having its lower end screw threaded and projecting through the body,the sleeve being provided with open ings registering with the fluidpassage of the body, a nut on the lower end of the sleeve, a cylindricalvalve mounted to slide in the sleeve and having an annular grooveadapted to register with the sleeve openings, said valve projectingbeyond the ends of the sleeve and provided with stops for limiting thesliding movement thereof, a springengaging one of the said stops forholding the valve with its groove out of register with the sleeveopenings, and means for sliding the valve to bring its groove inregister with the openings of the sleeve.
